ISPRINGEN, GERMANY. At embedded world 2017 in Nuremberg, Germany, Rutronik will be showcasing a cloud-connected thermostat demo based on the Microchip SAM L22 microcontroller (MCU), an ARMCortex-M0+ based processor family that continually receives high marks from EEMBC’s ULPBench low-power benchmarking test. In addition to efficiency, SAM L series MCU offer capacitive touch functionality via an LCD controller capable of providing up to 320 segments, as well as security features such as 256-bit AES encryption, random number generation, flash and tamper protection, and cyclic redundancy check (CRC).

The ultra-low-power (ULP) capacitive touch capabilities of the SAM L22 and other SAM L MCUs make them suitable for deeply embedded applications such as thermostats, utility meters, and medical systems. The devices are also outfitted with Microchip picoPower and low-power intelligent peripherals that operate independently of the CPU when it is in sleep mode. In particular, the SAM L22 features 256 kB Flash and 32 kB of SRAM, a crystal-less USB devices, programmable serial communications (SERCOM) modules, and Event System and Sleepwalking technologies from Microchip.

The SAM L22 can be evaluated on the Microchip Xplained development platform, which includes an on-board debugger and extension connectors. For more information, visit Rutronik’s booth (Hall 3A, booth 438) at embedded world. Ordering details are available at www.rutronik.com.
